Which encryption algorithm is the least secured?
Answer(s): C
DES (Data Encryption Standard) is a symmetric block cipher that uses a 56-bit key to encrypt and decrypt 64-bit blocks of data. It was developed by IBM in 1975 and adopted by the US government as a standard for encryption. However, DES has been proven to be insecure and vulnerable to various attacks, such as brute force, differential cryptanalysis, and linear cryptanalysis. A brute force attack can break DES in a matter of hours using modern hardware. Differential cryptanalysis can reduce the number of keys to be searched by a factor of four, and linear cryptanalysis can reduce it by a factor of two. Therefore, DES is the least secure encryption algorithm among the options given.

What is the command to check the status of the SmartEvent Correlation Unit?
Answer(s): B
The SmartEvent Correlation Unit is responsible for analyzing the log entries and identifying events from them. It runs on the Log Server machine or on a dedicated machine1. To check the status of the SmartEvent Correlation Unit, you can use the command cpstat cpsead on the machine where it is installed. This command will show you information such as the number of logs processed, the number of events generated, the CPU and memory usage, and the status of the connection to the SmartEvent Server23.

You need to see which hotfixes are installed on your gateway, which command would you use?
Answer(s): D
The command cpinfo y all displays information about all the hotfixes that are installed on the gateway1. This command also shows the hotfix ID, description, installation date, and status for each hotfix2. The other commands are not valid options for this task. The command cpinfo h all shows the hardware information of the gateway3. The commands cpinfo o hotfix and cpinfo l hotfix do not exist and will return an error message.

: 156VPN Link Selection will perform the following when the primary VPN link goes down?
VPN Link Selection is a feature that allows the Security Gateway to select the best link for each VPN tunnel based on the network topology and the Link Selection configuration1. When the primary VPN link goes down, the Firewall can update the Link Selection entries to start using a different link for the same tunnel, as long as the remote peer supports this feature and has multiple IP addresses configured2. This way, the VPN tunnel can be maintained without interruption or renegotiation. The other options are not correct because:A) The Firewall will not drop the packets, but will try to send them over another link if possible.C) The Firewall will not send out the packet on all interfaces, but will use the routing table to determine the best interface for each destination.D) The Firewall will not inform the client that the tunnel is down, but will try to keep the tunnel up by switching to another link.
